The orangina label says it contains lemons, oranges, and mandarins, but this recipe only uses mandarins (and I used oranges in mine actually).

In hindsight, I would juice a bag of mandarins and a couple lemons, mix it into real orange juice (not that sunny d crap), and mix the orange juice with mineral water and sweeten to taste. After its carbonated I'm sure it will be a nearly exact to the original product.
